Fix a bunch of missing expand calls in object/particle physics area, was breaking linking of those.

Initial report/patch by Alexander Gavrilov (@angavrilov), found more on the road.

Nice demo of why we should use libquery ID looper in read code too - but that's for another day
(also because read code needs to take care of some deprecated pointers sometimes)...
